Type
species:
Trachelas maculatus
(Thorell, 1875)
Diagnosis.
Paratrachelas
differs from
T. minor
, the
type
species of
Trachelas
by the presence of a chilum, a carapace with a broad cephalic part, the presence of a larger abdominal do scutum in males, AME closer to each other than to ALE, circular PME, stout male legs I and II with leg II longer than leg IV in most species, presence of leg cusps on ti, mt and ta of male legs I and II, a male palp without ve femoral groove or RPA and possessing a pointed RTA and a subtriangular bulbus which has a membranous conductor in most species, an epigyne with an anteriorly situated epigynal hood, as well as median COs connected to short and straight IDs, as opposed to the anterior COs and thin, coiled IDs connected to a longitudinally oriented median stretch ("median ducts of epigyne" of
Kovblyuk & Nadolny (2009))
in
T. minor
and related species, oval ST2 similar in size to ST1 and situated in between the latter (
Fig. 3
F, 4D), and sausage-shaped ST1 of which the two globular lumina are interconnected by intertwined solenoidal ducts (
Fig. 4D
).
Paratrachelas
differs from
Metatrachelas

are herewith transferred to
Paratrachelas
as well, as
P. v a l i d u s
new combination and
P. i b e r i c u s
